The advantages of Spring boot

spring bootCan support developers to quickly develop a restful style of micro-service architecture;

spring bootAutomation is really convenient, and the micro-service is suitable, single jar package deployment and management are very convenient. As long as the system architecture design is reasonable, large-scale projects can be used, coupled with nginx load balancing, easy to achieve horizontal expansion;
